RecyclerView的简单使用

• 首先需要依赖
  
  • compile ‘com.android.support:recyclerview-v7:24.2.1’
  • 后面的数字根据当前的v7版本
• 横向滑动的RecyclerView

 mRv_view = (RecyclerView) findViewById(R.id.rv_view);
        mRv_view.setLayoutManager(new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL , false));
        mRv_view.setAdapter(new MyAdapter());

• adapter中的ViewHolder去实现点击效果

class MyAdapter extends RecyclerView.Adapter<MyViewHolder>{
        @Override
        public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            MyViewHolder holder = new MyViewHolder
                    ( LayoutInflater.from(parent.getContext()).inflate(R.layout.item_gv_img , parent , false));
            return holder;
        }

        @Override
        public void onBindViewHolder(MyViewHolder holder, int position) {

            holder.mImageView.setImageResource(mimgs[position]);
        }

        @Override
        public int getItemCount() {
            return mimgs.length;
        }
    }

    private class MyViewHolder extends RecyclerView.ViewHolder  implements View.OnClickListener{
        ImageView mImageView ;
        public MyViewHolder(View itemView) {
            super(itemView);
            mImageView = (ImageView) itemView.findViewById(R.id.iv_img);
            mImageView.setOnClickListener(this);
        }
//getAdapterPosition() 得到点击的当前位置！
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplicationContext() , "click"+getAdapterPosition() , Toast.LENGTH_SHORT).show();
        }
    }
